Rechnungsfehler & Stornokosten (Invoice Errors & Credit Note Costs)
Definition
Manual PO systems frequently misalign with purchase order receipt quantities and rebate calculations. Common failures: (1) Quantity mismatch: PO for 100 units received/invoiced for 120 (data entry error); (2) Rebate not deducted: Invoice issued gross; rebate accrual recorded separately, creating reconciliation gap; (3) Price variance: Rebate tier not applied (vendor agreed 2% at €500k, but invoice shows 1%). Each error requires formal Gutschrift (credit note) issuance. Under new e-invoicing rules, credit notes must reference original invoice and be issued within 14 days; late or missing links trigger audit flags. Estimated impact: 8–15% of 10,000 annual invoices = 800–1,500 credit notes/year. Cost per credit note (processing, system entry, vendor follow-up, potential dispute): €20–50. Total: €16,000–€75,000/year. Additionally, customer friction from billing errors causes 1–2% order churn and 2–4 day DSO extension.
Key Findings
- Financial Impact: Credit note processing: €16,000–€75,000/year. Customer churn impact (1–2% lost orders on €20–50M revenue): €200,000–€1,000,000. DSO extension (2–4 days on €20–50M annual sales): €110,000–€550,000 working capital tie-up. Total financial impact: €326,000–€1,625,000/year per wholesaler.
- Frequency: Ongoing (10–50 credit notes/week typical).
- Root Cause: Manual rebate lookups and price verification at invoice time; no real-time validation against PO.
